Question

Three charges are fixed to an x,y coordinate system. A
chargeof 56.57 µC is on the y axis at y=+3.0m. A charge of-20µC is
at the origin. Last charge of 50µC is onthe x axis at x=+3.0m. A)
draw a picture. B) how manyelectrons make up the charge at the
origin? C) determine themagnitude and direction of the net
electrostatic force on thecharge at x=+3.0m. Specify the direction
relative to the xaxis.
